Everybody let's start a new gun registry, tell us exactly who has what. Real smart.
Given that the majority of T97's at this point have been purchased from a small number of retail dealers who bought from a single importer, a defacto registry of T97 owners already exists.
All the RCMP have to do is get a warrant to get the sales ledger from North Sylvia for the dealers who purchased from them, then get a warrant for the sales ledger from all those businesses of the owners who bought from them. They could then hire an analyst like me, who in 20 minutes could build up a fully detailed ledger of who owns what, when they bought it, how they paid for it, and the date they took delivery of it.
The old LGR was really nothing more than an excuse by the government to give hundreds of millions of dollars to CGI - a lot of well connected folks in Ottawa are really good buddies with them - and it was never a viable threat for wholesale confiscations of the firearms contained therein.
If you can log on to the the website of any of the dealers you bought your guns from and view a detailed history of your transactions - so can the RCMP. This is the information age - the government doesn't need to aggregate information in a centralized data store that they manage to know exactly who has what. "We" (and by "we" I mean the government) are also waging a war on terror - so they already have much of the infrastructure in place to be able to keep the public safe from potential terrorists (you and me).
That being said - the only deterrent from the government coming after people is realizing that thousands of potentially uncooperative businesses or individuals may or may not have them, and the amount of effort needed for them to go after them individually is more than they have resources to commit to.
Of course, once large numbers of T97's start showing up on the EE, that cat's out of the bag and there's nothing the government can do - if anything, T97's on the EE ought to carry a hefty premium for the insurance the sale guarantees the buyer of NOT being on an easily traceable ledger that the government can very quickly and easily retrieve.
On another note - unless you've put your address in your profile and user settings, the RCMP would basically have to get a warrant and serve it to GreenTips a warrant to seize his servers. The problem is that would likely cause outages on CGN and most certainly word of mouth about such shenanigans would spread even if CGN didn't go down. It would be an absolute PR nightmare for the RC's and the government if a website with over 100,000 active subscribers was raided to go after a handful of of lippy internet mall Ninja's.
Even the main stream media (who is in the government's pocket already) would go ballistic on them for doing so, as the sites like CGN are effectively the new media - it would set a clear precedent that the government is clamping down on the most revered constitutional right (especially by the main stream media): Section 2(b) of the Charter of Rights and Freedom - the "freedom of the press and other media of communication;"
In other words - there's safety in numbers.
